Abstract

Producing a plastic, comprises developing a solid perfume by performing encapsulation of a perfume element in a porous support by centrifugation, and introducing an additive and a plastic material prepared by simply mixing or by compounding. An independent claim is included for an item of furniture comprising the perfumed plastic obtained by implementing the above process.

Description

Translated from French

-1- 10 La présente invention a pour objet un procédé permettant de produire une matière plastique parfumée pouvant émettre et diffuser une odeur ou une fragrance pendant une période de temps relativement longue. -1-10 The present invention relates to a method for producing a perfumed plastic that can transmit and diffuse a scent or a fragrance for a relatively long period of time.Elle s'applique notamment, mais non exclusivement, à la production d'une matière plastique du type susdit, qui est utilisée afin de fabriquer des éléments de mobilier tels que des chaises et des luminaires, ou plus généralement des objets de design. It applies in particular, but not exclusively, to the production of a plastic material of the aforesaid type, which is used to manufacture items of furniture such as chairs and lamps, or more generally design objects.

De manière préférentielle, l'encapsulation du parfum ou du concentré de parfum s'effectue par absorption jusqu'à saturation dans un support poreux constitué par de la poudre de silice. Preferably, the encapsulation of the perfume or fragrance concentrate is carried out by absorption to saturation in a porous carrier consisting of silica powder.En outre, l'introduction de l'additif dans le polymère s'effectue préférentiellement par simple mélange dans l'hypothèse où l'on utilise de la poudre de polymère. In addition, the introduction of the additive in the polymer is preferably carried out by simply mixing in the case where use of the polymer powder.

Selon une variante d'exécution, un premier film polymère chargé en additif parfumé peut être laminé en écrasant de la matière fondue entre deux rouleaux. According to an alternative embodiment, a first polymeric film loaded with scented additives may be laminated by crushing of the molten material between two rolls.Ce premier film est relativement chargé en additif et peut être ensuite recouvert d'un autre film plastique par laminage de manière à obtenir 30 une bonne adhésion entre les deux films, voire les trois films si l'on rajoute une couche sur au moins l'une des faces. This first film is relatively laden additive and can then be covered with another plastic film by rolling so as to obtain 30 good adhesion between the two films, if the three films if we add a layer on at least the one of the faces.Le film laminé ainsi obtenu est utilisé préférentiellement pour effectuer de l'habillage d'objet ou d'intérieur. The laminate film thus obtained is preferably used to perform dressing of object or inside.2969622 -7- Selon une variante d'exécution préférentielle de l'invention, un colorant peut être introduit lors de l'étape d'élaboration de l'additif solide parfumé par encapsulation ou lors de l'étape d'introduction de cet additif dans une matière plastique. 2969622 -7- According to a preferred alternative embodiment of the invention, a dye may be introduced during the preparation of the solid additive step perfumed by encapsulation or during the introduction of the additive in step plastic.

Selon une autre variante d'exécution de l'invention, l'élément parfumé est intégré dans un support poreux au moyen de nano et/ou micro particules, organiques et/ou inograniques. According to another alternative embodiment of the invention, the perfumed element is incorporated in a porous medium by means of nano and / or micro particles, organic and / or inograniques.

10 La présente invention a également pour objet le dispositif constitué de la matière plastique parfumée issue de l'introduction de l'additif dans la matière plastique, ce dispositif consistant préférentiellement en un élément de mobilier tel qu'une chaise. 10 The present invention also relates to the device consisting of perfumed plastic Following the introduction of the additive in the plastics material, this device preferably consisting of a piece of furniture such as a chair.

14. Procédé selon l'une des revendications précédentes, caractérisé en ce qu'un colorant est introduit lors de l'étape d'élaboration de l'additif solide parfumé lors de l'étape d'introduction de cet additif dans une matière plastique. 14. Method according to one of the preceding claims, characterized in that a dye is introduced during the step of preparation of the perfumed solid additive in the introduction of this additive step in a plastics material.
